Time dependent calibration options specify a polynomial applied to the input to produce a calibrated output with the polynomial being optionally variable in time. The calibration is specified as a list of numeric coefficients in ascending power order, starting from the constant (x0). Each coefficient is a base ten decimal number with an optional fractional part. Additionally, leading zeros are ignored and numbers can be specified in scientific notation using 'e' syntax.

Coefficients are are delimited using , or ; or : with empty fields interpreted as zeros.

Identity
--switch=0,1
--switch=:1.0
Third order polynomial
--switch=0,1,2
--switch=-1E1:-2:0.5

If the option contains a / then it is treated as time dependent. In this context the value is split into fields separated by , with the first field being the interval and all further ones specifying the time range. This means that the coefficients in the first field are the polynomial for the time range specified in subsequent ones.
